Some test text!
Welcome to PDFTron. You can start with WebViewer in an Angular project from scratch or integrate it into an existing application.
This guide will help you integrate a free trial of WebViewer into Angular applications from scratch. It will help you clone the Angular sample repository, walk through the project structure, and show you how to call other WebViewer API. Your free trial includes unlimited trial usage and support from solution engineers.
by executing
```git
git clone https://github.com/PDFTron/webviewer-angular-sample.git
```
Once cloned, navigate into the webviewer-angular-sample
directory and install all the required dependencies by executing
npm install
npm will also download the PDFTron WebViewer and extract it to /src/lib
.
You are now ready to run the sample or use more WebViewer APIs.
After initial setup, the webviewer-angular-sample
directory should be laid out like this:
webviewer-angular-sample
├── angular.json
├── CONTRIBUTING.md
├── e2e
├── LICENSE
├── node_modules
│ └── ...
├── package.json
├── README.md
├── src
│ ├── app
│ │ ├── ...
│ │ └── app.component.ts
│ ├── files
│ ├── index.html
│ ├── lib
│ │ ├── ui
│ │ │ ├── ...
│ │ ├── core
│ │ │ ├── ...
│ │ └── webviewer.min.js
│ └── ...
└── ...
Notable files and directories include:
File/Folder Name | Description |
---|---|
LICENSE | Lists the PDFTron copyright and license information. |
files | Contains the sample PDF for the application |
lib | Contains the extracted WebViewer SDK |
index.html | Contains the main layout for the application |
app.component.ts | Contains the code for the main application, includes WebViewer instantiation as well as the 'documentLoaded' callback |
In short, app.component.ts
instantiates WebViewer and sets up some example event handlers. WebViewer is presented on the page using the <app-root>
router.
Since this is an Angular project, it is important to pay attention to the bundled files and assets. If you take a peek inside the angular.json
file, you'll notice the following lines inside the build
options:
{
//...
"assets": [
// existing assets can remain as they are
"src/lib"
],
"scripts": [
// other scripts you may have
"src/lib/webviewer.min.js"
]
//...
}
Please make sure that webviewer.min.js
is included in the scripts
and also that the lib
folder containing the webviewer.min.js
file is included in the assets
array so that WebViewer can function properly.
To run the sample, navigate to your webviewer-angular-sample/
directory and execute
npm start
Then navigate to http://localhost:4200
. You should see the application load on your browser. Note it will change in real time if you edit any of the source files.
To call more WebViewer API's, navigate to /src/app/app.component.ts
and add the API calls in the callback of the WebViewer constructor(you may need to make one if it is not provided).
WebViewer({
path: '../lib',
initialDoc: '../files/webviewer-demo-annotated.pdf'
}, this.viewer.nativeElement)
.then(instance => {
// In this callback WebViewer will be initialized, so you can call WebViewer API here.
instance.UI.setTheme('dark');
});
If your Angular application is already running, you should see the theme change right away. Otherwise execute npm start
again, then navigate to http://localhost:4200
and you should see that the theme has changed.
